<br/><font face="Verdana">General Description<br/>The LM78LXX series of three terminal positive regulators is<br/>available with several fixed output voltages making them<br/>useful in a wide range of applications. When used as a zener<br/>diode/resistor combination replacement, the LM78LXX usually<br/>results in an effective output impedance improvement of<br/>two orders of magnitude, and lower quiescent current. These<br/>regulators can provide local on card regulation, eliminating<br/>the distribution problems associated with single point regulation.<br/>The voltages available allow the LM78LXX to be used in<br/>logic systems, instrumentation, HiFi, and other solid state<br/>electronic equipment.<br/>The LM78LXX is available in the plastic TO-92 (Z) package,<br/>the plastic SO-8 (M) package and a chip sized package<br/>(8-Bump micro SMD) using National’s micro SMD package<br/>technology. With adequate heat sinking the regulator can deliver<br/>100 mA output current. Current limiting is included to<br/>limit the peak output current to a safe value. Safe area protection<br/>for the output transistors is provided to limit internal<br/>power dissipation. If internal power dissipation becomes too<br/>high for the heat sinking provided, the thermal shutdown circuit<br/>takes over preventing the IC from overheating.<br/>Features<br/>n LM78L05 in micro SMD package<br/>n Output voltage tolerances of ±5% over the temperature<br/>range<br/>n Output current of 100 mA<br/>n Internal thermal overload protection<br/>n Output transistor safe area protection<br/>n Internal short circuit current limit<br/>n Available in plastic TO-92 and plastic SO-8 low profile<br/>packages<br/>n No external components<br/>n Output voltages of 5.0V, 6.2V, 8.2V, 9.0V, 12V, 15V</font>
